Creating A Circular Frame-Help

I am new to this wonderful site!! I am hoping to find an answer to my question that I have been trying to figure out for days. I am creating a birthday invitation for my daughter and I want to make a circle frame and insert her picture into the frame. I have Elements 5.0 and CS3.
I am drawing a blank on how to do this!! It's driving me crazy because I cannot figure this out!!

You can use the shape tool to cut a circle out of paper and to crop your photo - just be sure you are working off a copy.
There are always lots of ways to accomplish something in PSE and PS, so you will probably get other suggestions. But Dee's would be the easiest.
